The international students who are going to the United States have a variety of questions to understand, and many people will consult with the study agent（also known as留学中介）.
First of all, most American schools require international students to vaccinate (also known as留学生疫苗接种). All freshmen must provide a complete vaccine record to attend classes. If they do not provide vaccine records according to the school requirements, they will not be allowed to enter the campus, and may even be liable.
The second problem is the insurance for international students (also known as留学生保险). The United States is the most expensive country in the world for medical expenses. Common outpatient and emergency charges can range from hundreds to thousands of dollars. If surgery is needed, it can cost tens of thousands to hundreds of thousands of dollars. Living in the United States without health insurance, at any time because of medical expenses and carry a huge amount of debt. Therefore, international students must purchase medical insurance. In addition to the insurance provided by the university, Huhu insurance (also known as虎虎保险) is also a good choice.
In addition, the legal status after graduation is also the most mentioned by many international students. After graduation, your student status expires and many people choose to apply for h1b visa. H1b visa is the most important type of work visa in the United States. It is a non-immigrant visa granted to foreign skilled workers employed by American companies. H1B visa holders can stay in the United States for three years, and then they can extend their stay for another three years. At the end of the six-year period, they must leave the United States if their status has not been changed. But h1b lottery (also known as h1b抽签) is as random and uncontrollable as winning the lottery.
You can also choose o1 visa. The O1 visa is a visa issued by the United States to work in the United States for persons of outstanding ability in the fields of science, art, education, business or sports. Compared with h1b visa, o1 visa is a little more difficult, but there is no lottery link, and it can be renewed once a year indefinitely if it meets the conditions.
